Demand Response & Grid Tariff Optimisation
KNX-based demand response: dynamic electricity tariff integration (Tibber, Nordpool API), SG Ready heat pump load shifting, KNX peak load management to avoid grid demand charges, and Home Energy Management System (HEMS) coordination between PV, battery, EV charger, and controllable loads.
Tibber and Nordpool Dynamic Tariff Integration with KNX
Integrating Tibber GraphQL API and Nordpool spot prices with KNX — Python bridge on Raspberry Pi for hourly tariff polling, DPT 5.010 tariff level GA, MDT logic blocks to enable or shed loads based on CHEAP/NORMAL/EXPENSIVE price level, and SG Ready heat pump coordination triggered by cheap tariff hours.
SG Ready Heat Pump Grid Optimisation with KNX: Four Operating States
Implementing the SG Ready standard (VDE 0755-95) four operating states via KNX relay actuator — MDT AKD-0800.01 wiring for S1/S2 binary inputs, KNX group address logic table, PV surplus state 3 trigger from Victron Cerbo GX Modbus, and grid peak shedding state 1 for demand charge avoidance.
KNX Peak Load Management: Demand Meter Monitoring and Load Shedding
KNX peak load management to prevent demand charge tariff spikes — Eastron SDM630 Modbus TCP demand meter, load priority shedding table (EV charger, underfloor heating, pool pump), hysteresis re-enable logic, EVBox OCPP Modbus current write for graceful EV pause, and MDT Glastaster II live demand visualisation.
